The Vestment of the Great Spirit is one of the more rewarding secrets in DragonSword: Awakening, and the good news is that it costs nothing. No quest chain, no currency, no locked region. The catch is that the chest holding it sits at the bottom of a deep underwater shaft northeast of the Firefly Forest, and reaching it without running out of stamina takes a bit of preparation.
Where is the Kalien secret outfit chest?
The chest containing the Vestment of the Great Spirit sits underwater to the northeast of the Firefly Forest. You do not need to unlock the region first, which means you can grab this outfit surprisingly early in the game.
Once you reach the marked water location, dive straight down. The descent is longer than it looks from the surface. At a certain depth, you will need to manually readjust your camera angle to keep moving downward rather than drifting sideways. Keep going until you reach the very bottom, where you will see a prompt near the chest. Press F to open it and the outfit is added to your collection immediately.

Chest location northeast of Firefly Forest
What stamina items do you need before diving?
Two consumables make this dive manageable: Egg Renew and Assorted Rice Bowls. Each one does something different, and using them together is the actual trick here.
The strategy is straightforward. Pop the Assorted Rice Bowls to cut your stamina drain in half for the descent, then use Egg Renew as a recovery tool the moment your stamina gets critically low. Combining both effects gives you enough runway to reach the chest without surfacing and losing progress.
How does the familiar deep dive ability help?
Before you even think about jumping in, make sure you have a familiar equipped that has the deep dive ability. This is not optional if you want a clean run. The ability conserves your stamina during the descent, which stacks with the Assorted Rice Bowls effect and gives you a much larger buffer to work with.
Without a deep dive familiar, you are burning stamina faster and leaning harder on the Egg Renew to compensate. The dive is technically still doable, but the margin for error shrinks considerably.

Equip a deep dive familiar first
Getting the Vestment of the Great Spirit
Here is the full sequence from start to chest:
- Obtain Egg Renew and Assorted Rice Bowls from your inventory or by completing the associated tasks.
- Equip a familiar with the deep dive ability.
- Travel northeast of the Firefly Forest to the underwater location.
- Dive straight down into the water.
- Activate Assorted Rice Bowls to reduce stamina consumption by 50%.
- Continue descending, adjusting your camera angle when the shaft narrows or changes direction.
- Use Egg Renew when your stamina approaches the minimum to restore 25% instantly.
- Reach the bottom and press F at the chest prompt.
- The Vestment of the Great Spirit is added to your collection.

Press F to claim the outfit
The whole sequence takes a few minutes once you have the consumables ready. The outfit itself is free, which makes it one of the better early rewards in the game for players willing to do a bit of prep work.
